I have files that are updated every 2 hours. I have to detect the files automatically and insert the information from them into a database. The files are simple text files and I know which part of them is useful for me. Our DBMS is Postgresql and programming language is python. what is your suggestion to do that? I want to make use of DAL (Database Abstraction Layer) or psycopg to make connection between the files and database and use postgresql LISTEN/NOTIFY techniques to detect the new files. if you agree with me please tell me how I can use LISTEN/NOTIFY functions to detect the files.
